Pending the arrangement by Bentham and Hooker, I have in somo instances (as in LUiacese) grouped plants more with regard to present convenience than to tho orders they will ultimately he placed in i a fault of no great importance in a work like the present. In the above table are counted only well-recognized species. Besides these, however, the volnme contains a large number of varieties more or less clearly separable from the speoies to which they are referred. Many of these doubtless wiU yet be recognized as distinct. As a rule, only the plants coUected by the various parties of this Survey have been enumei'ated or described in this Eeport. In tbe masterly contribution on the Ferns alone has this rule been ¦widely departed from. In it tho species ennmerated outside of those collected by the Survey, are not enongh to greatly affect tho above table. Though somewhat out of place here, I add'information received from Mr. watson relative to Dasylirion graminifolium, Zucc. (numbers 329,65i>), described on page 272, as the body ofthe text was stereotyped before the information was received, and as, further, there appears to be some' doubt as to tho practicahility of finding a more suitable place among " addenda et corrigenda." In 1871, Mr. Bischoff, of this Survey, collected and sent home seeds of this species. ITrom these, plants have been raised, and are now growing in the Cambridge Botanic Garden. After a careful study of the living and the dried speci¬ mens, Mr. Watson decides that it is a new species, .ind proposes for it the name of Dasylirion Wheelen. Ho states that it iliffers from D. graminifolium Zucc, "in the longer pendant racemes, the wings of tho fnut adnate only to the base of the style and prolonged above it, and apparently also by somewhat broader leaves." 379
